商品介绍

DNase I (Deoxyribonuclease I) is a dialyzed lyophilized powder from bovine pancreas that has been purified by chromatography.

Bovinepancreatic deoxyribonuclease (DNase) is an endonuclease which splitsphosphodiester linkages, preferentially adjacent to a pyrimidinenucleotide yielding polynucleotides with a free hydroxyl group at the 3"position and phosphate group at the 5" position. The optimum pH is 7.8.

DNaseI is activated by bivalent metals, and inhibited by chelating agentssuch as EDTA and SDS. DNase I can be stabilized against proteolyticdigestion by 5mM Ca2+.

Goldbio DNase is tested on bacterial lysates rather thanon pure DNA. Tests on pure DNA are not as rigorous andtend to be biased towardsuccess.

Product SpecificationsDNase IDeoxyribonuclease IDNase I, Bovine Pancreas, >300 Kunitz U/mg

MOLECULAR BIOLOGY GRADE

Unit Definition: One Kunitz Unit will produce an A260 of 0.001 per minute at pH 5.0 at 25°C using DNA, type I or III as the substrate.

Storage/Handling: Store desiccated at -20°C.Allow product to come to room temperature before opening.

Forgreatest stability, it is important that DNase to be dissolved at aconcentration of at least 1 mg/ml in 50% Glycerol with 20mM Tris-HCl, pH7.5, and 1mM MgCl2.

品牌介绍
D-荧光素钾盐/钠盐体内使用手册--Goldbio介绍   荧光素是一种常用的荧光素酶表达的活体成像生物发光报告子。以ATP和Mg2+作为辅因子,有氧条件下荧火虫荧光素酶与水溶性底物反应发出一种特有的黄绿色发射光,在37℃活体内转换为红光。该反应通过消耗ATP来指示是否存在能量或生命的存在。   D-荧光素在生物技术领域是一种常用的试剂,尤其在活体成像方面。荧光素酶被接种在研究动物中比如大鼠,小鼠,用来标记肿瘤细胞,干细胞或传染病。通过生物荧光成像这个模式系统中D-荧光素的注射可以用来实时,非侵入性监测疾病的进程或药物效率。   产品具体信息 D-荧光素钾盐 4,5-Dihydro-2-(6-hydroxy-2-benzothiazolyl)-4-thiazolecarboxylic acid potassium salt KC11H7N2O3S2 分子量:318.42 g/mol D-荧光素钠盐 4,5-Dihydro-2-(6-hydroxy-2-benzothiazolyl)-4-thiazolecarboxylic acid sodium salt NaC11H7N2O3S2.H2O 分子量:320.32 g/mol 储存:-20℃避光保存。
